I have the laptop acer aspire 5820TG (timeline X).
After I install windows 10 hdmi dot work at all. I tried everything I can think of. I install again windows 7 and it work fine. (At windows 7 there are some times problems with sound but this is happening all the time I know how to fix it, so this is ok for me) but I can't solve hdmi not working at windows 10.
Thank you in advance for any advice you might have.
